A savory sandwich featuring sweet caramelized onions, crisp apple slices, and melted sharp cheddar cheese.
# What You'll Need:
→ Caramelized Onions
01 - 1 large yellow onion, thinly sliced
02 - 1 tablespoon unsalted butter
03 - 1 teaspoon olive oil
04 - 1/2 teaspoon salt
05 - 1/2 teaspoon sugar (optional)
→ Sandwich
06 - 4 slices sourdough or country bread
07 - 2 tablespoons unsalted butter, softened for spreading
08 - 1 medium crisp apple (e.g., Granny Smith or Honeycrisp), thinly sliced
09 - 4 ounces sharp cheddar cheese, sliced or shredded
10 - Freshly ground black pepper, to taste
# Step-by-Step Guide:
01 - In a skillet over medium-low heat, melt 1 tablespoon butter with olive oil. Add sliced onion and salt. Cook, stirring frequently, for 15 to 18 minutes until onions are deeply golden and soft. Add sugar halfway through if extra sweetness is desired. Remove from heat and set aside.
02 - Arrange bread slices on a work surface. Spread softened butter on one side of each slice. On the unbuttered side of two slices, layer half of the cheddar cheese, followed by caramelized onions, apple slices, a pinch of black pepper, then the remaining cheddar. Top with the remaining bread slices, buttered side facing out.
03 - Heat a nonstick skillet or griddle over medium heat. Place sandwiches in the skillet and cook for 3 to 4 minutes per side, pressing gently, until bread is golden brown and cheese is melted. Reduce heat if bread browns too quickly.
04 - Remove sandwiches from heat. Allow to cool for 1 to 2 minutes, then slice and serve warm.
